Information about Submandibular Duct
) | |
| Dissection, showing salivary glands of right side. (Labeled as "submaxillary duct", but is identified as "submandibular duct" in newer sources.) | |
| Mandibular division of trifacial nerve, seen from the middle line. The small figure is an enlarged view of the otic ganglion. ("Wharton's duct" labeled in lower left.) | |
| Latin | ductus submaxillaris |
| subject #241 1135 | |
| MeSH | Wharton's+Duct |

It begins by numerous branches from the deep surface of the gland, and runs forward between the mylohyoideus, hyoglossus, and genioglossus, then between the sublingual gland and the genioglossus, and opens by a narrow orifice on the summit of a small papilla at the side of the frenulum linguæ.
On the hyoglossus it lies between the lingual and hypoglossal nerves, but at the anterior border of the muscle it is crossed laterally by the lingual nerve; the terminal branches of the lingual nerve ascend on its medial side.
It drains saliva from the submandibular glands and sublingual glands to the sublingual caruncle at the base of the tongue.

The salivary glands in mammals are exocrine glands that produce saliva. In other taxa such as insects, salivary glands are often used to produce biologically important proteins such as silk or glues.

The parotid duct is also known as koslo's duct. Saliva from the parotid gland passes through it to the mouth.
It pierces the buccal fat, buccopharyngeal fascia and buccinator muscle then opens into the vestibule of the mouth opposite the upper 2nd molar tooth.
